St. Patrick’s Day Cake: Green Velvet

By  | 

Ever wonder why we celebrate St. Patrick’s Day? That’s what my five-year-old, Sam, wants to know. After hearing he might get pinched on St. Patrick’s Day he came home from school and wanted to know, “why?” As I was developing some St. Patrick’s Day party food ideas for kids, I thought I should give him a bit more background on the occasion.

Growing up in Newfoundland, St. Patrick’s Day was a national holiday but most businesses remained open and we still had school. I knew about the parades celebrating Irish history and heritage. I knew about St. Patrick; his story contains all kinds of heroics that kids—especially boys—find fascinating.

St. Patrick was kidnapped from his home in Britain and he was taken to Ireland as a slave (he wasn’t Irish and his name wasn’t Patrick then!). After six years he escaped and returned to his home, where he studied at monastaries and became a priest and then a bishop. Patrick returned to Ireland and began sharing his Christian faith. He had a lot of adventures with the druids and pagan religions in the area. He used a number of the Celtic symbols to help explain Christianity. For example, he used the shamrock to explain the Holy Trinity. After living and serving in the area for about 30 years, the majority of the nation was converted to Christianity. St. Patrick died in Ireland of natural causes on March 17—our St. Pat’s Day.

I knew most of that background about St. Patrick but I didn’t know why if you didn’t wear something green to school, you were considered a fair target for pinching. I didn’t find out why until Sam began interrogating me and I went hunting for answers. Supposedly, if you wear green, you become invisible to Leprechauns. Leprechauns have a reputation for being cranky little fellows who mend the shoes of fairies and cause all kinds of mischief. The pinching serves as a warning to remind you about Leprechauns. I don’t think that tradition has anything to do with the real St. Patrick!
